Suppose your state lottery has an expected value of
−34%.
if you spend $40 per month on lottery tickets, how much money would you be expected to lose in an average year?
we can expect to lose $
.

$163.20

Step-by-step explanation:

Your state lottery has an expected value of −34%.

You spend $40 per month on lottery tickets. So, you can expect to lose 34% of the amount you spend.

Find 34% of $40:

Hence, we can expect to lose $13.60 per month.

A year (12 months period) expected lose is

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
